AI Technical Summary

Technical Problem

In the prior art, the control of the charging socket lamp requires the VCU and OBC to determine the AC charging status respectively, resulting in duplicate software development workload and a large amount of hardware resources.

Method used

A controller (first controller) is used to control the DC charging socket lamp and the AC charging socket lamp, and connect the second controller through the CAN bus to achieve unified control of the AC and DC charging socket lamps.

Benefits of technology

It reduces the difficulty of OBC software development and hardware resource utilization, reduces the cost of vehicle development, and displays different charging statuses through LED lights of different frequencies and colors, making it easier for users to observe the charging status of the vehicle.

Abstract

The present application provides a control circuit, method, device, vehicle and storage medium for a charging socket lamp. The circuit includes: a first controller includes a three-primary color drive circuit and a DC grounding switch, the three-primary color drive circuits correspond to the three-primary color LED lamps in the DC charging port socket and the AC charging port socket, and the DC grounding switch is respectively connected to the three-primary color LED lamps in the DC charging port socket; the second controller includes an AC grounding switch, and the AC grounding switch is respectively connected to the three-primary color LED lamps in the AC charging port socket. The present application can use the first controller to control the DC charging socket lamp and the AC charging socket lamp, thereby reducing the difficulty of the second controller software development, reducing the hardware resource occupation of the second controller, and thus reducing the vehicle development cost.
